=== WRITING RULES ===

Voice Requirements (MANDATORY):

- [ ] Specific timestamp or location in first paragraph
- [ ] At least one quote from a real person or internal monologue
- [ ] "I thought... but..." pattern somewhere
- [ ] Admit one thing you got wrong
- [ ] Mention the cost: time, sleep, relationship friction

Structure Requirements:
- Hook: timestamp + location + crisis in first 2 sentences
- Struggle: build tension through failed attempts
- Moment: the realization or break point
- Fix: what worked, with explicit caveats/tradeoffs
- Reflection: "I learned..." (not "you should...")

Forbidden:
- Generic setup instructions
- "Best practices" without personal context
- Tutorial-first structure (story-first, tutorial-second)
- Polished conclusions that hide the struggle
